which gripper is right for me?

I'm looking at the ironmind captains of crush ones but I'm hesitant to order cause I cant try em out at the store because they seem to be only available online. If anyone here trains with ironmind tell me which ones I should buy given the following stats about myself.

-I dont have particulary large hands or wrists and I only weigh 140lbs
-I DO have relateively big forearms for my size that are hard as rocks
-"Normal" handgripes (ex lifegear) are like absolutely nothing for me (I close about 50 reps before getting bored)
-I deadlift 250 lbs without support straps and my back gives out before my grip/forearms do.

I'm looking for a pair of grippers I can close for 6-10 reps and no more than 15

Start with a Ironmind Trainer. Most commercial grips are a joke and the trainer will give you a chance to accurately gauge your grip strength. If it's no problem (you can close it 20 times or more), then you can head up to the No. 1. If you can't hit that many reps, you can work the trainer.

I'd start with the #1 and #2 personally, that what I did, I couldn't even get the #1 parellel, within 2 weeks of casual use I was able to close it, it really helps to advance having a harder gripper to do negatives.

I'm 6'3" and 160, so I'm pretty scrawny myself. A pair? You only buy store grippers in the pairs :P At least go with the trainer and #1 if you're getting some.

kraker, before you consider buying a "captain of crush", have you considered using your normal handgripper as follows?:

A - closing it against the palm of your hand with index and middle fingers only (no thumb)
B - closing it with the thumb against the index and middle fingers.
C - closing it against the palm of your hand with the pinky and ring fingers only (no thumb)

I'm in the same situation as you. I can close my pedestrian handgrip until the cows come home, but I can only do 8 reps of A, and about 5 of B. For C, I can only do one, and after that, I have to my other hand to close it and then use it for negative reps.

I'm not sure if this it's a better approach, not sure if it's even a reasonable one, but (at least for me), I'd like to see how much gains I can make with the gripping variations I just mentioned before going for a captain'crush - nothing against them, just one of the experiments I'm currently doing :)

The street argument is retarded. BJJ is so much overkill for the street that its ridiculous. Unless you're the idiot that picks a fight with the high school wrestling team, barring knife or gun play, the opponent shouldn't make it past double leg + ground and pound - Osiris
